VENTILATING SWEAT-LEATHER FOR HATS.

Speccaton of Letters Patent No. 30,648, dated November 13, 1860.

To all whom it 'may concern:

Be it known that I, JULiUs PoLLocK, of Morrisania, Westchester county,and State of New York, have invented a new and useful Improvement inVentilating Sweat- Leathers for Hats; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figure l is a perspective view represent ing myimproved sweat leather as applied to a hat; and Fig. 2, a sectionthereof.

The same letters indicate like parts in all the figures.

Hats have been made with a hollow cushion inflated with air to avoid thepressure on the forehead, and combined with tubes or corrugaticns in thesweat leather at the sides of the head just over the temples, LettersPatent for such a combination having been granted to me bearing date the3rd day of April, 1860; but in practice it has been found difficult tomake such cushions air proof and when originally made air proof theysoo-n leak and become disagreeable to the wearer. And it has also beenfound iii practice that the corrugations at the sides of the hat soonflatten out and then fail to admit of the required circulation.

The Object of my present invention is to avoid the defects above stated,and to this end my said invention consists in making sweat leathers forhats with embossed projections to bear on portions of the forehead, andfilling in the cavities on the side next the hat with some light andelastic substance, such as loose felt, possessing sufficient elasticityto yield to the form of the forehead, and tension enough to prevent thesaid projections from being permanently pressed out of shape. And mysaid invention also consists in forming such sweat leathers with crimpedor embossed corrugations at the sides stiflened on the inside withsliellac or equivalent gum or cement, so

' as to retain them in form that air may circulate through them.

In the accompanying drawings (a) represents a hat of suitable shape and(b) a sweat leather applied to the inside and there secured in the usualway. That part of the sweat leather which fits over the forehead isembossed fro-in the side next the hat to form hollow protuberences (o,o) at any desired distance apart on the side next the forehead, leavingspaces between for the passage of air. The cavities so formed are to befilled in with felted fabric (CZ) very slightly felted so that it shallbe very elas tic and light, that it may readily yield to the headwithout materially increasing the weight of the hat.

At the sides of the sweat which, in use, come over the temples, thesweat is crimped or embossed into corrugations (e, e) extending entirelyacross the sweat. The inner surface of these corrugations is to be wellcoated with shellac or other equivalent cement varnish which will not besoftened by moisture from the head. In this way the corrugat-ions willbe retained in form while in use so as to leave free passages for thecirculation of air.

What I claim as my invention, and desire to secure by Letters Patent,is-

Making single sweat leathers for hats with embossed protuberences at anydesired distance apart, filled in on the side next the hat with somelight and elastic substance, substantially as described, to formyielding cushions against the forehead,l as set forth.
